humboldt roots

i was wondering if anyone has used humboldt roots and how early can you start adding it to your water? it says to use 1-2 ml per gallon, how am i suppose to measure that? is it like a drop?

Never used it man. But I gotta shout to the locals. HUMBOLDT BABY!!!!

half teaspoon is 2.5ml, so maybe just mix up a larger batch so you can measure it properly and you're not just guessing. you could also go on ebay and pick up a syringe or two, since cc's are the same measurement as ml's.

well if 1/2 a tsp is 2.5 ml, then 1/4 tsp would be 1.75 ml which would work because i can use 1 - 2 ml per gal. thx man. still wondering if anyone has ever tried this stuff
